Yes. You may sign a National Letter of Intent before you receive your final certification determination from the NCAA Eligibility Center. When you sign a National Letter of Intent you agree to submit the necessary information and documents to the Eligibility Center. These documents do not have to be received by the Eligibility Center before you to sign a National Letter of Intent. If you are classified by the Eligibility Center as a qualifier, the National Letter of Intent is considered valid. If you are classified as a nonqualifier pursuant to NCAA Bylaw 14.3, your National Letter of Intent is rendered null and void.
